I agree - it's absolutely impossible to work out what Sinnick could have meant, due to his most egregious one-letter typo.

All surviving cryptanalyists from the wartime Bletchley Park team have been brought back together to try to crack this most opaque of sentences.

Experts believe that a sentence has not been so hard to understand since Reginald Knobtrouser accidentally put a superfluous apostrophe in a possessive "its", and inadvertently started the Hundred Year's War.

Incidentally, before some other pedant points it out, I used an apostrophe in the title in "PM's". Some dictionaries say this is Ok if it helps with clarity. More of a modern problem, because we have more acronyms nowadays. Just saying.

When acronyms first became prevalent I always used an apostrophe. Although technically wrong of course, it provided a buffer between the upper case and lower case characters. It just seemed too weird to write things like PCBs or EEPROMs. They look ok now though.

Also, some very early word processor software didn't allow you to have a capital letter other than at the beginning of a word. So NewsBiscuit would have been a nono.
